IMPROVEMENT IN BEER-COOLERS.

Specification forming part of Letters Patent No. 127,639, dated J une 4,1872.

To all whom it may concern:

Be it known that I, J oHN MARTIN OTTO, of Brooklyn, E. D., in the countyof Kings and State of New York, have invented a new and usefulImprovement in Beer-Coolers; and I do hereby declare the following to bea full, clear, and exact description thereof, which will enable thoseskilled in the art to make and use the same, reference being had to theaccompanying drawing forming part of this specitication, and in whichdrawing- Figure l represents a transverse vertical section of myinvention. Fig. 2 is' a plan or top view of the same. Similar lettersindicate corresponding parts.

This invention relates to an improvement in the construction of theordinary shallow cooling-pan generally used in breweries; saidimprovement consisting in the arrangement of T- irons under the jointsbetween the several sheets of iron which constitute the bottom of saidpan, in such a manner that by such T- irons the bottom is strengthenedand the edges of the sheets of iron are prevented from bulging up,thereby producing a flat and even bottom, which is a great desideratumin coolingpans. The rim of my pan is formed by bending the extreme edgesof the outer sheets upward to the desired height; andsaid rim isstrengthened by an gie-irons, which are riveted to it, extendingthroughout its entire length and Width.

In the drawing, the letter A designates a cooling-pan, which isconstructed of a series of iron plates or sheets, a, of suitable lengthand width, the length of such sheets being gencrally eight feet andtheir Width three feet. These sheets are placed edge to edge, and theyare secured by means of T-irons b, 'which are fastened'to the sheets byrivets c, as shown in Fig. l.

By means of these T-irons the joints between the several sheets arerendered tight and perfectly hat, the sheets being eftectually preventedfrom bulging up, so that a cooling-pan is obtained which is durable andin which the operation of cooling can be carried on With ease andfacility.

' The T-irons which I use are generally eighteen feet long, so that thesame extend beyond the length of two sheets, whereby the strength of thepan ismaterially increased. For the cross-seams I cut the T-irons inpieces of suitable length. The rim d of my pan is formed by bending theextreme edges ofthe sheets upward. to the height of about six inches;and in order to strengthen this rim I secure to its edges the angle-irons e, which extend all round the rim.

By these means a cooling-pan is obtained which is superior in strengthand durability to cooling-pans as heretofore constructed; and, byapplying to the bottom plates of my pan the T-irons b, said plates arermly retained in position, and they are eiectually prevented frombulging up.

What I claim as new, and desire to secure by Letters Patent, is-

1. The arrangement of T-irons b under the joints of the metal plates a,which constitute the bottom of al cooling-pan, A, substantially asdescribed.

2. The angle-irons e, in combination with the rim d of thefpan A,substantially as set forth.
